Abstract: ABSTRACT OF THE DISCLOSURE     GASIFICATION OF CARBONACEOUS SOLIDS           Disclosed is a process and apparatus for the continuous gasification of carbonaceous solids, such as coal, coke, peat, etc.  The process involves the downward flow of a fluidized solid particulate heat-transfer material through a vertical vessel countercurrent to the upward flow of a reactive fluidization gas.          Subdivided carbonaceous solids are introduced into a central portion of the vessel and substantially flow downwardly through the vessel and react with the upflowing fluidization gas.  The vessel is divided into at least three zones:  an upper zone, an intermediate zone, and a lower zone.  In the lower zone the fluidization gas is heated by the downflowing solid heat transfer material.  In the intermediate zone, the carbonaceous solids react with the fluidization gas forming a product combustible gas and transferring heat to the heat transfer material.  In the upper zone, the downflowing heat-transfer material is heated by the upflowing fluidization gas.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus for developing latent electrostatic images on dielectric carrier sheets has a rotary cylinder whose periphery supports a carrier sheet with a latent image thereon, and a metallic block having a concave surface which constitutes a grounded electrode and defines with the exposed side of the carrier sheet on the cylinder a narrow gap of constant or gradu-ally decreasing width, as considered in the direction of rotation of the cylinder.  The block has alternating fluid admitting and fluid-evacuating orifices which communicate with the gap and extend transversely of the path of movement of the carrier sheet.  Each fluid-admitting orifice is nearer to the preceding than to the next-following fluid-evacuating orifice, and the width of the fluid-evacuating orifices exceeds the width of the fluid-admitting orifices.  The block is located below the cylinder and the fluid-evacuating orifices communicate with a collecting tank into which spent developing fluid flows by gravity.          The fluid-admitting orifices receive pressurized fresh developing fluid from a pump.  Each unit volume of freshly admitted fluid dwells in the gap for the same interval of time because some of the fluid issuing from a fluid-admitting orifice flows forwardly toward the next-following fluid-evacuating orifice at a speed higher than the speed of the remainder of the fluid issuing from the same fluid-admitting orifice and flowing backwards toward the preceding fluid-evacuating orifice.

Abstract: ABSTRACT OF THE DISCLOSURE           In accordance with illustrative embodiments of the present invention, well logging data in analog or digital form is recorded by a cathode ray tube recorder.  A rep-resentation of the CRT beam is repetitively swept across a recording medium while being modulated with representations of the well logging signals.  This modulation varies as a function of the rate of change of the well logging signals to produce an even density recording.  Coding of the recorded lines or traces and the areas between selected traces can be accomplished.  This coding of the lines is also varied in dependence on the well logging signal rate of change to produce a uniform coding presentation.  Depth information can be recorded on the recording medium by writing depth numbers and depth lines on the record medium.  Moreover, a section by section visual presentation of the data can be produced while it is being recorded.

Abstract: ABSTRACT OF THE DISCLOSURE Methods of heating and welding together portions of a metal part or parts in which the portions are positioned in facing, generally parallel and spaced apart relation and with the spacing between the portions not greater than five times the thickness dimension of one of the portions.  By means of induction coil or loop means, oppositely flowing currents having a frequency of at least 3000 Hz are caused to flow in such portions until welding temper-ature is reached at which time the portions are pressed together to form a weld therebetween.  The spaced portions may be moved in the direction of their widths during the flow of the currents and pressed together at a downstream weld point to perform continuous welding or if the portions are on the ends of shafts or tubes, such shafts or tubes may be rotated during the flow of currents to produce a weld between the ends.  If the coil or loop means is a continuous conductor, at least two portions of the conductor extend on oppos-ite sides of and generally parallel to the portions to be heated and are spaced from the latter by a distance at least equal to ten times the refer-ence depth of the currents in at least one of said portions to be heated. Similar results may be obtained by supplying the currents to one of the por-tions to be heated through a pair of conductors connected to contacts at the ends of the one portion and positioning at least a portion of one of the con-ductors generally parallel to the other portion to be heated and spaced from the other portion by a distance at least equal to ten times the reference depth of the currents in the other portion.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus are provided for continuously extruding, biaxially orienting and intermittently forming molded products from a web of thermoplastic material and further, con-tinuously separating the products from the web selvage, stack-ing and handling the products and recycling the web selvage for further extrusion.  The method and apparatus use intermittent molding devices into which configuration the biaxially oriented web is interfaced by a continuous to intermittent interfacing structure which preserves the dimensional and orientational integrity of the web and maintains thermal stability therein.          An undulating peripheral surface on a dynamic storage or accumu-lator drum and associated transfer rollers cooperate with inter-mittently advanced feed belts in timed relationship with a re-ciprocating forming press to effectuate the interface and pro-duct forming portions of the process.  Products are formed in the intermittently advanced lengths of the oriented web so that the stress placed on the thermoplastic material by the biaxial orientation is substantially maintained from the initiation of the orientation to the forming of the products therefrom.  In some of the preferred embodiments the inertia at the interface between the undulating peripheral surface of the accumulator drum and the biaxial orientation apparatus is reduced to an optimal minimum.  The present invention provides a system which is very facile and variable with regard to unique and unusual shapes.  This invention provides a means for interfacing between a continuous extrusion and orienting mode and intermittent form-ing mode without either mode effecting the integrity of the other or the quality and integrity of the biaxially oriented thermoplastic material in the system.

Abstract: PROCESS FOR THE RECOVERY OF URANIUM       FROM A SALINE LIXIVIANT             Abstract of the Disclosure A process for the recovery of uranium from a saline alkaline lixiviant employed in a uranium leaching operation.  An ion exchange resin is employed to adsorb uranium from the lixiviant.  Prior to contacting the resin with the lixiviant, the pH of the lixiviant is reduced to a value of less than 7.  By this technique, the resin loading in the presence of chloride ion is materially increased.  The pH values for optimum resin loading capacity decrease as the salinity of the lixiviant increases.  Resin loading is also enhanced by the presence of bicarbonate ion in the lixiviant.

Abstract: ABSTRACT             The control system and method of start-up are for a gas turbine power plant having an air-cooled pressurized fluidized bed combustor for generating combustion gases from the burning of pulverized fuel in the presence of crushed dolomite.  The plant also has a gas turbine engine connected to be driven by the combustion gases and for driving an air compressor which provides compressed air for cooling, fluid-izing the bed and supporting combustion of the fuel in the fluidized bed combustor.  In addition, the plant is provided with a free power turbine which is connected to drive an alternator and to be driven by gases exhausted from the gas turbine engine.  The control system has, for start-up opera-tion, various valve-controlled by-pass conduits for preheat-ing compressed air before entry into the fluidized bed com-bustor, diverting compressed air for cooling from the fluid-ized bed combustor and diverting exhaust gases around the free power turbine.  The valve-controlled by-pass for divert-ing exhaust gas around the free power turbine also functions to quickly adjust the output of the free power turbine to reductions in load thereon and, upon sudden loss of load, prevents destructive overspeeding of the free power turbine without disruption of the function and thermo-dynamic balance of the fluidized bed combustor and gas turbine engine.
